Positive tests for anterior impingement in 480 men and 672 women

Positive test for anterior impingement	Men, number (%)	95% CI	Women, number (%)	95% CI
Right hip	25 (5.2)	3.2–7.2	18 (2.7)	1.5–3.9
Left hip	24 (5.0)	3.0–7.0	22 (3.3)	1.9–4.6
Unilateral	21 (4.4)	2.5–6.2	24 (3.6)	2.2–5.0
Bilateral	14 (2.9)	1.4–4.4	8 (1.2)	0.4–2.0
At least one hip (worst)	35 (7.3)	5.0–9.6	32 (4.8)	3.1–6.4

The 95% CIs were calculated using binomial CIs.
